摘要
为了研究沥青及其混合料在长期老化后性能的变化,采用延度试验机、动态剪切流变仪对木质素纤维改性沥青、氧化石墨烯(GO)改性沥青以及木质素纤维-GO复合改性沥青的老化性能进行了研究,并对其混合料的水稳定性能、低温抗裂性能及四点疲劳性能进行了研究。结果表明,木质素纤维-GO复合改性沥青混合料的抗老化性能最佳。
In order to study the properties of asphalt and its mixtures after long-term aging,the aging properties of lignin fiber modified asphalt,graphene oxide(GO)modified asphalt and lignin fiber-GO composite modified asphalt were studied by using the ductility testing machine and dynamic shear rheometer.The water stability,low temperature crack resistance and four-point fatigue properties of the asphalt mixture were studied.The results show that the lignin fiber-GO composite modified asphalt mixture has the best anti-aging performance.
